A Gastroscopy is a procedure where a thin, flexible tube called an endoscope is used to look inside the esophagus (the gullet), stomach and first part of the small intestine – (duodenum). During the procedure a thin flexible tube (endoscope) with a small video camera at the end is passed through the mouth into the stomach. The end of the endoscope contains a light and conveys images to a TV monitor allowing the doctor a clear internal view of the lining of the esophagus, stomach and duodenum. The doctor can see abnormalities such as ulcers through the endoscope which are not easily detected on X-rays. As well as viewing the lining tissue samples (biopsies) can be taken for analysis. The tissue is removed painlessly by forceps passed down the endoscope. The test is usually carried out to investigate swallowing difficulties, nausea, vomiting, reflux, bleeding, indigestion, abdominal pain or chest pain.
